HANDLE FOR WINDING-ARBORS.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed November 11, 1905. Serial No. 286.895-

To all whom, it Hui/y concern:

Be it known that we, WILLIAM F. WINS? LOW and GEORGE B. OWEN, citizens of the United States, residing at Winsted, in the county of Litchfield and State of Connecticut, have invented a new and useful Handle for- Winding-Arbors, of which the following is a specification.

This invention is a handle, and while it is capable of universal use it has been primarily designed for use in connection with the winding-arbors of clocks.

The object of the invention is to enable I the convenient folding of the handle for convenience in storage and transportation, and in this connection it is proposed to provide for holding the handle against accidental displacement when folded and also when in its operative position.

A further object of the invention is to enable the application thereof to conventional forms of winding-arbors for clocks without requiring any change therein.

With these and other objects in view the present invention consists in the cornbination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of the handle of the present invention in its operative condition and applied to a winding-arbor. Fig. 2 is a side elevation thereof, showing the handle folded. Fig. 3 is a detail perspective view of the head of the handle. Fig. 4 is a detail view of the crossbar of the handle preparatory to assemblage with the head.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

Referring at first more particularly to Fig. 3 of the drawings ,it will be seen that the present handle includes a substantially cylindrical head 2, having an integral tubular stem or socket 3 extending axially therefrom and internally threaded. The head is pierced by a diametric opening 5, and at each end of the opening there is a notch or seat 6, formed in the periphery of the head and intersecting the opening. The other element of the handle is a cross-head consisting ofawirerod or bar 7, which is thrust through the opening 5 and. has its ends bent into spring-loops 8 and 9 to form finger-pieces upon the cross-bar. Preparatory to assemblingthe cross-bar with the head only one loop 8 can be formed therein, the other loop 9 being formed after the bar has been passed through the opening 5. The loops are so'proportioned that the free extrernities 10 of the bar constitute spring elements to' lie within the seats or recesses 5 in either position of the cross-bar, so as to hold the cross-bar against accidental turning.

As hereinbefore indicated, the present handle has been especially designed for use in connection With the winding-arbors for the mainsprings of clocks, a conventional form of winding-arbor being shown at 1 and car rying the usual ratchet-wheel 4, one end of the arbor being threaded into the stem or socket 3, whereby the handle and arbor may be assembled Without altering the latter. When the handle is in use, the cross-bar is rotated to bring the finger members at the outer side of the head with the spring elements 10 snapped into the outer ends of the seats or recesses 6, and when the handle is not in use it can be rotated so as to bring the finger-pieces at the inner side of the bar with the spring elements 10 snapped into the inner endsof the sides 6, and thereby held against accidental movement.

Among the advantages of the present invention it will be noted that as the middle portion of the cross-bar passes through the head there is no possibility of the bar being sprung out of the opening 5, while at the same time the bar may be conveniently rotated upon its straight portion 7 from one position to the other. Moreover, as the spring extremities 10 of the bar engage the seats or notches 6 at opposite rotatable limits of the bar the latter is effectually held against with the head to prevent endwise movement of the bar.

2. A handle comprising a head pierced by an opening, and a bar rotatable in the opening with its ends bent to form finger-pieces projecting at one side only of the bar and engaging the head to prevent endwise movement of the bar.

I 3. A handle comprising a head provided with diametricallyopposite seats, and a crossbar having its interi'nediateportion connected with and rotatable upon the head said bar having elements to engage the seats and prevent accidental rotation of the bar.

4. A handle comprising a head pierced by an opening with seats at the ends of the opening, and a handle-bar rotatable in the opening with its ends provided with finger-pieces projecting upon one side only of the bar and also provided with spring elements to snap into the seats and hold the handle bar against rotation at its opposite limits.

5. A handle comprising a head pierced by an opening and provided with notches intersecting the opposite ends of the opening, and a handle-bar rotatable within the opening and having its ends bent into loops projecting at one side only of the bar with the free extremities of the bar constituting spring elements to snap into the notches and hold the bar against rotation at its opposite limits.

6. A clockkey pierced by a diametric opening and provided with notches inter secting the ends of the opening, and a handlebar rotatable in the opening with its ends bent into loops lying at one side only of the bar, the free extremities of the bar forming spring elements to snap into the notches to hold the bar against rotation at opposite limits of its movement.

7. A clock-key having an opening and a rotatable handle-bar having an intermediate portion extending through the opening and provided at its ends with finger-pieces projecting at one side only of the bar and. capable of swinging past the shank of the key when. the bar is rotated, said finger-pieces ingaging opposite sides of the key to prevent endwise play of the bar.

8. A handle comprising a head, and a handle-bar having its middle portion rotatably mounted upon the head and its ends projecting beyond the head and provided with finger-pieces projecting at one side only of the bar and capable of swinging past the head when the bar is rotated.

9. A handle comprising a head, a handlebar having its intermediate portion mounted upon the head and its ends projecting beyond the head and provided with fingerpieces projecting at one side only of the bar and capable of swinging past the head when the bar is rotated, there being an engagement between the finger-pieces and the head at opposite limits of rotation of the bar to hold the bar against accidental rotation.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
